To all whom it may comma-11 Be it known that l, lIEINnIon DREWELL, engineer, a subject of the German Emperor, residing at Hanover, 26 Dieteriehsstrasse, Germany, have invented certain new and useful Improvements in ltlechanism for Perforating the Operating-Bands of Automatic TypeSetting Machines; and 1 do hereby declare the following to be a full, clear, and exact descri )tion of the invention, such as will enable otfiers skilled in the art to which it' appertains to make and use the same.

ln mechanism for perforating the operating bands of automatic type setting machines the perforating device has been combined with a typewriting machine so as to give the compositor a control over the matter set up. It is necessary to combine with such an arrangement a space indicator or letter counter which will record the widths of the letters set difference in these widths. This indicator shows the compositor when a hne is approxiefi'ected be'ore commencing a new line. Such apparatus causes the attention of the compositor to be of necessity divided between the matter written by the typewriting machine and the index of the space indicator.

The object of the present invention is to avoid the disadvantages of thus dividing the attention of the compositor, and is attained to print characters of difierent widths, being provided with mechanism for imparting step y step motion to the carriage this motion f connection of a ty ewriter provided with a corresponding to the width of any letter the key of which is struck. Such a typewriting letters are of uniform. widths and the carthe-form of typewriting machine it is proposed to use the widths of the letters and the carriage motioncorresponding to the widths type setting machine and are reproduced resulting from the de ression. of the keys of theitypewriting mac me. It will thus be seen that the length of the line of characters written by the typewriting machine bears a definite relation to the length of the corre sponding line which will be produced when t e type are set up before justifying hastaken place. As a result of this arrangement the compositor is enabled to separate the lines correctly and he can moreover bring parts of a line into any desired position with relation to its length. As for example when prearing a perforated band for setting up tabuated matter it is possible to so arrange the lines that the corresponding figures in different columns are exactly beneath each other, the disposition of the matter as written by the typewriting machine corresponding to the disposition that will result after the type is set up. This arrangement is possible in consequence of the lines as written by the typewriting machine and as formed by the set up type being both constituted of pieces, that is to say letters, whose widths correspond or are proportionate to each other so that not only does the whole of the typewritten line bear a definite proportion to t e length of the line of set up type but also any portion of one line bears a definite proportion to the corresponding part of the other line. As a result of the ossibility of bringing the matter produced by the typewriter into exact agreement as regards s ace division with the matter to be printe as symbolically reproduced on the band, leaving justifying out of the question, the compositor is able to obtain on the typewriting machine as correct a representation of the finished job as is possible. The attention of the compositor by this means has not to be divided and the resent invention therefore offers a special a vantage as compared with the known devices where a separate space indicator has to be employed.

The drawings show diagrammatically the paper-carriage shl ting device and with a perforating apparatus for making register strip? T e essential point of the present mvention is the systematic shifting of the pa eroarriage in such a manner that the lengt of the shifting is in a constant proportion to the width of the written t e which is simultaneously placed in symbo ic characters on the register strip. In other respects the construction of the typewriter machine'and of {3 erforating apparatus may be of various- In the accompan g drawings, in which the same parts are dZ iloted by the same reference characters,

Figure 1 is a vertical longitudinal section of the entire arrangement, Fig. 2 shows the at opposite faces of said wheel.

wheel which is provided 'at both sides with ratchet-teeth, said wheel turning. with the pinion 3 and moving the rack-bar 2 The shaft 4 is su ported insuitable bearings of the machinerame. The pawls 6 and engage alternately with the teeth of the wheel 5 The pawl 6 is loosel pivoted to a sleeve 7 which is loosely l a ratchet-wheel 5. The spring 9 rests against a plate 8 which is attached to the sleeve 7 and which turns with the same.

On depressing a key the corresponding ke lever. 14 presses with its lugs 15 on two ra1 s of the combination rails 13. One of the rails 13 acts on an elbow-lever 11 and the other on one of a series of angle-levers 20, shown in Figs. 1 and 3. On the arm 12 of the elbow-lever 11 is supported atransverse bar 16 which on depressing a key moves the pawl6 out of en agement with the teeth of the ratchet-whee 5. The sleeve 7 and plate 8 are thereby released by the wheel 5 and turned by the tension of a spring 17 (Fig. 2)

in such a manner that the plate 8 abuts against one of the stop-pins 1'8 Immediately before the pawl 6 is. removed from the ratchet-Wheel 5, the other awl 10 acts on the opposite side of the whee on the arm 12 of the elbow-lever-ll and enters into Y of the pawl '10 from the same.

the teeth of the ratchet-wheel 5 and holds the same firml in position during the depression of the ey.

The stolp-pins- 18 serve for the purpose of.

limiting t e movement of the plate 8, and thereby of the pawl 6. In their normal position the sto pins do not project into the path of the p ate8. By deplressing a key one of the elbow-levers 20, whic act on the stoppins 18 is actuated besides the elbow-lever 1 1 and thereby one of the pins 18 pushed forward so that the lpushed forward the length of motion of the p ate 8 is controlled.

When the key is released the elbow-lever -11 is first returned and permits then the successive engagement of the pawl 6 with the teeth of the ratchet-wheel5 and the release carriage is drawn under the influence of the well-known actuating spring (not shown) towards the-left (seelFig. 2). g It turns thereby ced on the shaft 4 so that it can be moved y a spring 9 clear of the'teeth of the late 8 is arrested. Ac-' cording as one .or t e other of the. stop-pins '18 is The paper-.

therefore dependent on the oscillations of the plate 8, and these again are controlled by the stop-pins 18, one of which is pushed forward during the depression of the key; By the arrangement described the, desired proportion between the length of the shiftin motion of the paper-carriage and the width of the printed or set type is obtained.

For the purpose of obtainingsimultaneously with the writing a symbolic setting of the type, the erforating app'aratusis connected with t e' typewriter machine. For this purpose the key-levers 14 actuate a second row of combination rails 22, shown'in Figs. 1 and 3, whic-h actuate a perforating apparatus of any suitable construction. With the combination rails 22 are connected draw-rods 24 by means of arms 23, said draw-rods being moved in downward direction against the tension of springs 25 during the depression of the key. The draw-rods 24-carry. on spring-actuated extensions interposed pieces .26 which enter during the downward motion between the punching-dies 27 and the bar 28. The latter is-connected with an arm of the lever 29, the other arm of which carries an armature '30 of the punchingelectromagnet 31. Below the arms 23 is located a movable insulated rail 35. This rail is connected with one end of thecoil of the electromagn'et 31, while the other end is connected with a source of elec-- tricity 34. The opposite pole of the source of electricity is connected with the machine, frame and is thereby connected with the arms 23 of the combination rails 22. As soon as one of the arms 23 contacts with the rail 35 the electromagnet is excited and attracts its armature. The'bar 28 is thereby moved towards the punching-die 27. At the points at which the interposed f pieces 26 are brought between the bar 28 and the corresponding punching-die by the key depression, the latter is forced through the paper 36. During the return of the bar 28 and of the punching-die 27 the upper end of the lever 29 acts on a shifting device 37 which consists of a ratchet-wheel and pawls and which produces thereby in the wellknown manner the forward motion of the paper strip 36. When the paper-carriage arrives at its end position, and the new line is to be commenced,; then the pawl 6 is moved by means'of a lever '38 out of engagement with the ratchetwheel"5 without the simultaneous entry of the pawl 10 into the ratchet-wheel. The ratchet-wheel is then free and permits thereby the free return motion of the paper-carria e in the pro er position for beginning a new ine.

. aving now particularly described and as certained the nature of my said invention, and in What manner the same is to be performed I declare that what I claim is:

1. In mechanism for perforating the operating bands of automatic type-setting machines, the combination of a perforating device, a typewriting machine constructed to print characters of different widths, and operative connecting means between the perforating device and the keys of the typewriting machine.
